There's a lot there, but if I'm following this correctly the answer to 
your question of whether you should have been able to anticipate that 
the wait could account for this Mac anomaly is no, and thankfully no 
will need to deal with it again once the Cocoa build is done because the 
need to do that for that one platform goes away then.

>> Hi Jerry,
>> The "with messages" clause makes a repeat loop non-blocking. This allows you to run multiple handlers with repeat statements simultaneously. I add the wait with messages command at the end of the loop to give the engine more time to update the GUI. Particularly in older versions of LiveCode, it makes a huge difference.

>>> In a nice example from Mark S., I see the line below. I've never seen the "with messages" part on the end of a repeat statement. I tried it, and it compiles and runs without complaint. What does it do, allow messages at the end of each repeat? I don't see it in the dictionary. I'm running LC Community 6.6.1 .
